Definitions

  • the invention also relates to an arrangement for charging capacitors of a direct-voltage intermediate circuit of a frequency converter, the arrangement comprising voltage connections to a voltage supply unit of the direct-voltage intermediate circuit, a positive bar and a negative bar of the direct-voltage intermediate circuit, a charging circuit of the direct-voltage intermediate circuit, a switch of the charging circuit and a by-pass switch of the charging circuit, capacitors corresponding to inverter parts connectable to the direct-voltage intermediate circuit, the first pole of the capacitors being connected to a positive bar of the direct-voltage intermediate circuit and the second pole being connectable in connection with a negative bar of the direct-voltage intermediate circuit by means of a charge switch and/or a main switch of the capacitor.
  • the solution according to Figure 2 further comprises a supply charging circuit CC, which is placed in the negative bar between the negative voltage connection U- and the charging circuits of the inverter parts.
  • the supply charging circuit CC comprises a switch KA of the charging circuit and a component AA limiting the current of the charging circuit and connected in series with the switch. Connected in parallel with this series connection, there is a by-pass switch KB of the charging circuit, by which the charging circuit CC can be bypassed.
  • said component limiting the charging current may comprise one or more resistors or direct-current choppers, the general operating principle and structure of which is known per se to a person skilled in the art.
